The BIG ideas for the Nervous System

Below are our objectives for the next two weeks.  You will get a copy of these objectives tomorrow in class.  The blank at the start of the objective is for you to write down the date(s) what you learned this material.  The blank at the end of the objective is for you to give yourself a score on how well you understand the material.

____N.1 State that the nervous system consists of the central nervous system (CNS) and peripheral nerves, and is composed of cells called neurons that can carry rapid electrical impulses. ___

___N.2 Draw and label a diagram of the structure of a motor neuron. Include dendrites, cell body with nucleus, axon, myelin sheath, nodes of Ranvier and motor end plates. ______

___N.3 Explain the levels of organization in the peripheral nervous system. ______

___N.4 State that nerve impulses are conducted from receptors to the CNS by sensory neurons, within the CNS by relay neurons, and from the CNS to effectors by motor neurons. ______

___N.5 Define resting potential and action potential (depolarization and repolarization). ______

___N.6 Explain how a nerve impulse passes along a non-myelinated neuron. ______

___N.7 Explain how the movement of Na+ and K+ ions to create a resting potential and an action potential.  ___

___N.8 Explain the principles of synaptic transmission. Include the release, diffusion and binding of the neurotransmitter, initiation of an action potential in the post-synaptic membrane, and subsequent removal of the neurotransmitter. ______

___N.9 Compare Parkinson’s Disease and multiple sclerosis with respect to the ways in which neurons are effected ______

___N.10 Identify factors which can lead to changes in communication between neurons.____

___N.11 Describe the major structures and functions of the vertebrate brain. ______

___N.12  Summarize the diversity of nervous systems in living things. _____

Always be thinking about how what you are learning relates to the themes of the course
